Growth and population dynamics of the Indian white prawn Penaeus indicus H M Edwards from Kakinada

Abstract

The von Bertalanlfy parameters of growth in Penaeus indicus are estimated as L,=218.9 mm, K = 2.0 per year, and to=O,O1 year in females and 227.2 mm, 1.8 per year and -0,0729 year, respectively in males. The instantaneous rates of mortality are estimated as Z= 9.42, M = 3.30 and F = 6.12 in femalcs and 12.73, 2.90 and 9.83, respectively in males. Various morphometric and length-weight relationships are worked out. At the current rate of fishing, the yield in weight per recruit is 23.05 g in females and 31.74 g in males. There is scope to increase the yield of this species by increasing F (i.c. effort).
